Geneva: UN human rights chief Navi Pillai
on Thursday slammed the Sri Lankan government for its refusal to
launch a credible investigation into the war crimes its forces
committed on Tamils in the final phase of civil war in 2009.

"Sri Lanka has failed and never participated" in
any credible process to look into the complaints on war
crimes, Pillai said at a press conference here.

"There is an imperative for the international
community to take further action" based on the documentary
evidence and visual testimony, she said arguing that the
special rapporteur on extra judicial killings had analysed
additional video evidence.

"So there is very high level of expectation
expressed by member states that Sri Lanka should enquire into
these allegations and have an open-ended process," Pillay
said.

Several western governments, including the US, have
called on the Sri Lankan government to address the allegations
of war crimes and start a process of reconciliation.

The UN has said up to 7,000 civilians were killed in
the final months of the fighting and a recent UN report
accused government forces of executing rebel leaders who were
said to have worked out a surrender.

An estimated 100,000 people were killed in the nearly
four-decade-long Tamil separatist conflict, which began in
1972.
